【摘要】 探讨了有限域GF(2n)上椭圆曲线密码算法基本理论、快速实现和ECDSA算法(椭圆曲线数字签名算法)实现的相关理论;然后采用INFINEON公司的携带域上求模运算的加速协处理模块(DDES-EC2)的智能卡芯片SLE66CL160S和SLE66CX320P,实现了基于有限域GF(2n)上密钥长度为163bits的椭圆曲线数字签名算法,并对这两种实现进行了对比分析;最后对实现进行测试,证明是成功高效的。更多还原

【Abstract】 Elliptic curve cryptosystems theory and the fast implementation of element algorithms over GF ( 2n) and algorithms of ECDSA arediscussed, then based on the SLE66CL160S and SLE66CX320P smart cards with embedded the DDES-EC2 module, the 163bit length ECDSAlogarithm over GF ( 2n) is implemented, and the two kinds of implementation are implemented. At last through testing, the result shows that thisimplementation is efficient and correct.更多还原
